It is nice to see BMW at least gave the 1M a little more in the tune over a standard N54. They obviously could have put out much more if they wanted to. 346 wheel horsepower in STD correction is pretty darn good for with an intake. That is basically M3 power right there. The car is rated at 335 crank so when a vehicle is putting out more to the wheels than it is rated at the motor that is definitely what we call underrated. This leads us to believe the reason the 1M did not get the DCT transmission is it would have stepped all over the M3's toes.

Also Sticky, you need to mention in the original post that it has an Injen Intake already on it. I mentioned this in one of my previous posts, just put it up there to clarify so people dont go buckwild.

Sure I would have liked it with the S65 underneath the hood, but if it indeed comes with an Alpina built engine, then BMW has played a trump card on all of us by keeping this quiet til the very end. If it was a regular run of the mill N54 then I wouldnt care less what this car can do. A built engine, even if it is a turbo one, in my eyes makes it all the better.

This is what it should have been but I don't believe it as it would have at least an engine designation change then.

That's a huge difference. It's almost comical how underrated this car is. It puts down MORE then the advertised crank HP numbers!!!! wtf!

well crank advertised hp is 335. Most people put down 320ish completley stock. Even so, only 15hp loss is slight, considering most 335s lose 25-30hp to the wheels (300 stock, most dyno in the 270 range), so I wouldnt be surprised if it was more.

There might be a slim chance that it might be redynoed with no intake. The dealer is $#@!ing about having to drive a modified car while its in their paint shop to fix the hood (has a factory defect, about a dozen small non-glossy blotches on the hood, and a weird paint line straight up the right side of the hood), but I dont understand why they need to drive it if its just going in for a hood repaint.

@Matt@Camber-Toe what is it that is different about the 1M n54 as compared to other n54's? You posted about someone telling you it was different but didn't really say what other than speculation about being Alpina built. Where did that stem from?

Jeremy from OE Tuning has speculated due to the fuel and ignition maps looking identical to the Alpina setup, whereas a regular N54 was entirely different.

i guess we wont know until someone tears it down and we see for ourselves. 292 seems awfully low , if it was a mustang dyno maybe?
